CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:S/C:P/I:P/A:N
Base score: 5.5

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 2.51%
Percentile among all scored CVEs: 84
Score date: 10/9/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
